rron, or MILWAUKEE, wrsoonsrmn CORPORATION ROAD-RAIL STAKE BOX Application filed January 12, 1928. SerialNo. 246,207.

The employment of road rails or forms in connection with the construction of concrete roads necessarily involves the problem of holding the rails in position on the subgrade 5 in a very positive and rigid manner in order to. insure the best results. Conventional practice dictates the use of stakes in conjunction with stake boxes which are affixed to the rail, the stake passing through openings in both the box and rail and on into the ground, whereby therail is held in place.

Difliculties of varying degrees have been encountered inthe assembling of the boxes and the rails. It is of utmost practical importance to provide a connection between the box and the rail or form which permits of their ready'assembly in the field, i. e., at the place where the form is to be used, rather than at the factory, without sacrificing to any degree the rigidity of the connection between these parts.

In accordance with the above indicated ideas, this-invention provides a stake box that is positively fastened to a rail or form in a novel and simple manner, this being made possible by the construction of the box including hook members which enter slots in the rail and thereby engage the same, the engagement being engendered by a downward movement of the box after the hook members have been inserted in the openings.

In order to prevent upward movement of the box relative to the rail, which movement would permit of the disassembly of the boxes, means are provided for fastening the box to the base of the rail whereby the connection between the two is made positive in every respect.

Further and more detailed objects will in art become apparent and in part be hereinafter stated as the description of the invention proceeds. For a more complete understanding thereof reference may be had to the following description and accompanylng drawings in which:

Figure 1 is a perspective view showing my improved stake box mounted on a road rail or form. I

Figure 2 is a vertical section taken through the rail showing the box inside elevation.

Figure 3 is a fragmentary showing bringmg out the arrangement of the hook members in the slots, these members being shown in section. v

Figure 4 is an enlarged, detailed view illustratin'g the position of the hook members in the slot immediately upon its insertion therein.

Figure 5 is an enlarged, detailed view showing the hook member in the slot after the former has been moveddownwardly. 1

While a single embodiment of the invention is herein set forth it is to be understood that I am not to be limited to the exactconstructions illustrated and described, because various modifications of these details may be provided in putting the invention into practice within the purview of the appended claims. c

A convention type of road rail orvfor'm is shown in Figure 1 and is designated by the reference character A. This rail comprises, generally, inner and outer faces 1 and 2 which are connected at the top by the arcuate portion 3 constituting the top surface of the rail on which a finishing machine is adapted to ride. The face 2 terminates at the bottom in a flange 4,-which is in engagement with a flange 5. The flange 5 is formed by continuing the face 1 and bending the same as indicated at 6. The flanges 4 and 5 may be held adapted to receive fastening elements, passing through portions of a stake box.

My improved type ofstake box is shown at 10 and comprises the side members llvand 12, connected by the top portion 13. The top portion 13 is provided with an opening 14 which, when the box-is in position, will respect to the slots 8. These openings 9 are r be in substantial alignment with an opening in the base portion of 'the rail or form comprising the flanges 4 and 5. The box 10 is so designed that the top portion 13 bears against the face 2 of the rail at a point above the upper extremities of the slot 8. The side members 11 and 12- have continuations 16 which are cut away at 17 to provide hook members. The cut away portion 17 is of substantially the same thickness as the face 2 of the rail A. i The hook members 16 have the same longitudinal dimensions as the slot 8 so that they may pass therethrough. It will be obvious that upon inserting the member 16 in the slots 8, so that the cut away portions 17 are in alignment with the face 2, the box may be moved downwardly to afford a rigid connection between the side members and the rail. At their bottoms these side members 11 and 12 terminate inflanges 18 having openings therein. The openings in the flanges 18 are aligned with the openings 9 in the base portion of the rail or form. After the hook members 16 have been properly engaged with the side faces of the rail the rivets 19 are availed of to not only fasten the flanges 18 to the base portions of the rail, but also to fasten the flanges i and 5 constituting said base portion together. It will be apparent that this provides for a very rigid and simple connection between the stake box and the rail. A stake 20 passes through the openings 14 and 15 and into the ground to properly position the rail. A wedge 21 may be employed by passing the same through openings 22 in the side members 11 and 12 to provide a rigid connection between the stake and stake box.

It is to be clearly understood that while I have shown one type of hook engaging means between the side members and the rail adjacent to the upper portions of the same, widely varying constructions at this point could be designed to accomplish the same purpose. The same applies to the manner in which flanges 18 are aflixed to the base portion of the rail. Obviously these members could be soldered or welded thereto, as well as riveted.

WVhat might be said to be one of the underlying principles of my invention is to provide a so-called detachable connection near the upper portion of the stake box and a permanent connection at the bottom which cooperates with the upper connection to prevent the disjoining thereof.

Having thus described my invention what I claim as new, and desire to secure by Letters Patent of the United States, is:

1. A road rail or form of'the class described, comprising, in combination, a rail member having an inclined wall formed with slots therein, a stake box, and hook members 'upon the stake box inclined complementally to the sloped wall-ofthe rail and cooperating therewith in aflixing the said box to the said rail.

2. A road rail or form of the class deportion of the rail whereby disengagement of the hook-members from the rail is prevented.

3. A road rail or form of the class described, comprising, in combination, a rail member having a wall formed with vertically extending slots therein, a stake box, books on the stake box adapted to enter the slots in the wall, and means associated with the rail for preventing upward movement of the hooks, whereby disengagement of the hooks from the wall is prevented.

4:. A stake box of the class described, comprising, in combination, a main body portion having spaced walls, books on said spaced walls adapted to be brought into engagement with the wall of a rail, and flanges at the bottom portion of the box adapted to be fastened to the bottom flange of the :rail to prevent upward movement of the box after the same has been affixed to the rail through the medium of the hooks.

In testimony whereofI aflix my signature.

GEORGE H. MILLER.
